ON Semiconductor NCP81071AZR2G Dual Channel Gate Driver

The NCP81071AZR2G from ON Semiconductor is a high-performance dual channel gate driver designed to drive N-channel MOSFETs or IGBTs in a synchronous buck converter topology. This advanced gate driver is ideal for a variety of applications, including computing power supplies, server and telecom power systems, as well as general-purpose DC/DC converters.

Featuring a wide supply voltage range from 4.5V to 18V, the NCP81071AZR2G provides a robust and flexible solution for different power management scenarios. Its two independent driver channels can be configured for high-side and low-side operation, making it versatile for different circuit designs and topologies.

One of the key features of the NCP81071AZR2G is its high peak current capability, with source and sink currents of up to 4A. This ensures fast and efficient charging and discharging of the gate capacitance of power MOSFETs, leading to reduced switching losses and improved power efficiency. Additionally, the adaptive non-overlapping control prevents shoot-through by ensuring that the high-side and low-side MOSFETs do not conduct simultaneously.

The device also boasts robust protection features, including under-voltage lockout (UVLO) for both VCC and VBST, which ensures the gate driver operates only when the supply voltage is within the acceptable range. Moreover, the NCP81071AZR2G incorporates a thermal shutdown feature to protect the device under extreme thermal conditions.

With its small footprint, the NCP81071AZR2G is available in a compact, thermally efficient 10-DFN (3x3) package, making it suitable for space-constrained applications. Its excellent thermal performance also helps in maintaining system reliability and longevity.

Overall, the NCP81071AZR2G dual channel gate driver from ON Semiconductor is a high-quality, feature-rich solution for modern power management systems, providing designers with a dependable and efficient component for their high-speed switching applications.
